AS Roma defender Leandro Castan undergoes successful brain surgery

Castan, a Brazilian center back, had complained of dizziness during a match against Empoli in September, his only appearance of the season. Subsequent tests revealed a congenital vascular alteration in his brain, the team said in November, and he was scheduled for surgery.

The surgery took more than three hours to remove the three-centimeter blood vessel which caused Castan's condition. He will remain in an intensive care unit for 24 hours.
